Looks like you're having as much fun as I am. I have decided to take the time to cut and place a second sheet of 1/16" balsa between the ribs and on the back side of the TE sheeting. If I am to handle the wing any more, the support really needs to be there. The last thing I need is to have the underlying structure weak after I put the covering on. So, I will begin after work today and will be using Titebond glue. Won't need pics of this process since once the sheeting is in place, it will be hidden anyway. Using the titebond will also get me away from the CA for a couple of days. Between the balsa dust (yes I used a mask while sanding) and the CA fumes, I have watery/burning eyes, and am sneezing quite a bit.

rcken/dmanson:
I do have one question though. Did you find it difficult to add the wingtip sheeting on the front of the wingtip? It seems to me that this appears to be a compound curve. Maybe it isn't, but I haven't bent balsa in a shape like this before. I almost considered adding solid balsa wingtips, but decided to try the way that is indicated. Any help on this would be appreciated.
